I'm having DHCP issues when connecting an unmanaged switch to my Cisco 2960 switches. I have the port it is connected to set to access VLAN1 which is the native vlan for all traffic. Some computers are able to connect and receive DHCP perfectly. A static IP printer is also running off the unmanaged switch and is able to be accessed from all parts of the network. I have statically assigned IP's to those computers that do not receive an IP and I'm able to ping any PCs connected to the unmanaged and I'm not able to ping internet domains or the file servers upstream from the unmanaged switch. I'm guessing that multicasting is not travelling back up to the 2960 from the unmanaged switch. I need a little help in understanding how to set up the 2960 to communicate properly with the unmanaged switch.
The unmanaged switch is an SMC 10/100. I need to get this running temporarily until i'm able to run homeruns back to the computer room into a newly acquired space.
